Fig. 1 has described the calcspar that is used for comprising according to one embodiment of the invention the image detection and the video receiver of the extraction of choosing wantonly.Video receiver 100 comprises TV, set top box or digital video cable, satellite or terrestrial broadcast receiver, and it comprises the tuner (not shown) that the energy broadcast program that demodulation received is play.Person of skill in the art will appreciate that the whole structure of video receiver and be operated in this and be not described or illustrate.Yet the present invention can be used in conjunction with the video receiver of routine, and on the only this degree to understand the present invention necessary or to the unique video receiver of the present invention structure be operated in this and be described and illustrate.
Fig. 2 A-2C is used in sample image that the control based on video content of video information recording is used and corresponding template according to one embodiment of the present of invention.Fig. 2 A and 2B are used for the sample video image that the user wishes the video information that writes down, are the figure that is used to present weather conditions from the news weather forecast in this example.Can not watch the news program that comprises weather forecast or dislike watching whole forecast or the user of the record of the whole news forecast of fast-forward search process, still may wish to watch weather forecast.
Fig. 2 A is similar with image 200,201 major parts among the 2B, and can be used to obtain corresponding image template 203.White region 204a-204e in the image template 203 is the variable zone that different information or content can occur, and is left in the basket between the comparable period for video information identification and matching and that received.Although be described to rectangle in example embodiment, the white space of the 204a-204e shown in those or zone can be any shapes arbitrarily.
Coupling is to discern with the video field or the frame that are received by the remainder of movement images template 203 (rather than white space).When the field that receives when detecting or the predetermined extent of the similitude between frame and the image template, coupling is considered to definite.
Although the image template 106 with the form shown in the image template 203 among Fig. 2 C limits the spatial distribution and color characteristic in the zone that is compared at the similitude degree. in the example of Fig. 2 C, be shown as whole audience image, a little and specific part that image template 106 can only comprise (being the major part that white region covers) with relative little white region.For example, image template can be defined to catch the bar on the bottom, and this provides, and motion is kept the score, " massaging device (ticker) " of the operation of stock price or collection of choice news.
Image template 106 can be generated or input by receiver, video information connects 103 and sends to video receiver 100 by the user.In other words, template 106 can produced at a distance, or the utilization broadcast medium (for example cable, satellite or terrestrial broadcasting or the Internet flow) identical with video program play to be demodulated and that show or send to video receiver 100 by different connections.
Most of contemporary broadcast mediums comprise into hundred passage, this make movement images template 106 and institute to some extent the content of reception be unpractiaca.Therefore, program 105 preferably includes the additional information of discerning content to be recorded with 106 related being used to of each template, as passage, time cycle, programm name or description and/or close title (closed-caption) keyword.Such additional information by image processor 102 be used for initial select by with corresponding templates 106 video information that is received relatively.The template 106 that provides from external source can be bundled with this related additional information, and described information can be used or modification by the viewer.
The additional information related with specific template 106 preferably includes passage and programm name, comprises content to be recorded, and it can be hunted down from Electronic Program Guide.Additional information also can comprise Advanced Television Systems Committee (ATSC) close-caption text (close-caption text) of a segment standard or from the keyword of described text, described text is from the relevant portion or the adjacent part of playing programs.For example, in the example of 2C, term " weather " and " forecast " can be used to search for close-caption text at Fig. 2 A.Specify be used to extract image template one or more to see under the situation of part of program the user, reprocessing to close-caption text can be manual, minimum user interface requirement is arranged simultaneously, or automatically, by eliminating stop-word and assigning to carry out at the cross part that several examples are sought close-caption text.
The additional information related with template 108 by program 105 be used for control channel or by the selection of the broadcasted content of video receiver 100 demodulation and sequential so that with corresponding template relatively.Close heading message can further dwindle after the keyword in detecting close-caption text by and corresponding templates relatively to the scope of the part of the broadcasted content of predetermined period.
As already pointed out, template 106 can be created in the video receiver 100, distributes to the subscriber or downloads by the Internet from each provenance by broadcast transmitted or physical medium (for example CD-ROM).For example, advertiser can generate and allow the user to catch the template of the commercial advertisement that is produced by this advertiser.Is similar in the template that produces beyond the video receiver 100 on final content, but can obtain or be loaded with video " key " or " watermark " (the unique image pattern that is used for the quick identification coupling) of being embedded into from bigger training set, and therefore more likely have precision preferably.
Template 106 that receives from external video receiver 100 and related additional information and video receiver 100 in those of generation can or delete by subscriber's change.Image template 106 all can be changed by the subscriber with related additional information.
If the nonvolatile memory 104 in the video receiver 100 is hard disk drive or other medium with enough capacity, the broadcast program that the is received broadcast that then comprises matching image is stored in the content 107 that is write down.Otherwise the connection such as USB (USB) in the video receiver 100 can allow matching content to be exported to external equipment, as video cassette recorder, read-write digital versatile disk (R-W DVD) unit or personal computer.
Image of being preserved or image sequence (being with or without related audio and/or close-caption text) can be retrieved so that watch from the content 107 that is write down by the subscriber.Such image also can be used as the example that is used to form template (positive and negative).The user also can be allowed to the content of managing image thesaurus 107, preserves or delete selected image as required.In addition, perhaps under interchangeable situation, automatically administration functionality can be provided so that the image of being preserved is retained up to having found new coupling at the template of correspondence, and perhaps N youngest image is retained, and wherein N is the positive nonzero integer of being selected by the user.
